질문 내용 :

Imagine you are standing in a Kansas field of ripened corn, staring up into a blue summer sky. Imagine the acre around you extending upward, in a transparent air-filled tunnel soaring all the way to space. That long tunnel holds carbon in the form of carbon dioxide ― widely implicated in global climate change. But the corn standing all around you holds four hundred times as much carbon as there is in the man-made carbon dioxide in the entire column. Yearly, we manage, through agriculture, far more carbon than is causing our greenhouse dilemma. Take advantage of that. The leftover corn from our fields can be gathered up, floated down the Mississippi, and dropped into the ocean, sequestering its contained carbon. It’s not a permanent solution, but it would buy us and our descendants time to find better answers. And it is inexpensive; cost matters.
문장구조나 구문이 어렵지은 않은데, 전체적인 내용이 옥수수밭 상공에 탄소가 많이 배출되어 지구기온에 영향을 미친다는 얘기인가요?

답변을 몇 분이 해주셨는데 제가 정확히 이해를 하지 못해서, 그리고 또 답변의 의견이 서로 약간 다른 거 같아서 다시 올립니다.
